This report describes earthquake engineering designs presently used for earth fills, and discusses the concepts and problems concerned with such designs along with the results of failure tests on earth fills carried out by use of a large vibrating table as they relate to slip calculations. The types of earth fills covered include the fill dam, the levee, a railroad embankment, a road embankment, and an artificial island for a transverse road across Tokyo Bay. It was found that a reduced modified seismic coefficient rather than the estimated maximum seismic coefficient may be used in the calculation for stability analysis, and that if the dynamic excessive pore pressure produced in the soil is introduced in the calculation of slip, the phenomenon of failure can be explained with good results. In conclustion, it was noted that more data are needed from comparative experiments of the effect of earthquake proof measures for earth fills.
